How does mass affect rate of reaction
Did you know?
WebFeb 2, 2024 · For the reaction rate to have units of moles per liter per second, the rate constant must have reciprocal units [1/ (M·s)]: kM2 = M s k = M/s M2 = 1 M ⋅ s = M − 1 ⋅ s − 1 B The exponent in the rate law is 2, so the reaction is second order in HI. WebMay 12, 2024 · Increasing the concentration of reactants generally increases the rate of reaction because more of the reacting molecules or ions are present to form the reaction products. This is especially true …
